A rapid dehydration forming equipment for concrete prefabricated parts

Abstract

The invention relates to a quick dehydration molding device for a concrete prefabricated member. The device comprises a vacuum tank and at least one buffering tank. The buffering tank is provided with multiple connection pipes communicated with the inside of the buffering tank, and at least one connection pipe is communicated with the vacuum tank. When the device is used, the device is connected with a die through the connection pipes, and filter cloth does not need to be arranged in the die; by means of the arrangement of the vacuum tank and the buffering tank, vacuum storage amount is increased, the technical problems that if a vacuum machine works for a long time, the vacuum degree greatly fluctuates and water absorbing is accelerated are solved, water absorbing time is shortened, production efficiency is improved, production cost is lowered, and sewage, impurities, cement thinner and the like are sucked into the buffering tank through the connection pipes; filtering is achieved through a filtering device, the sewage, the impurities, the cement thinner and the like can not enter the vacuum machine, and the vacuum machine can not be damaged.

Description

technical field [0001] The invention relates to equipment for producing concrete prefabricated parts, in particular to a rapid dehydration forming equipment for concrete prefabricated parts. Background technique [0002] The building exhaust system includes an exhaust pipe and a hood on the top. The exhaust pipe is used to remove the smoke generated by the kitchen cooking activities or the pipe products of the bathroom. It is also called the exhaust duct, the ventilation duct, the residential exhaust duct, the residential The exhaust duct is the main component of the common exhaust duct system for residential kitchens and bathrooms. [0003] In order to improve the production efficiency of exhaust pipes, hood top covers and other cement prefabricated components, most of the exhaust pipes, hood top covers and other cement prefabricated components are produced by molds. During the production process through the molds, the concrete slurry After being injected into the mold, it...

AI Technical Summary

Problems solved by technology

[0009] The patents disclosed above are all vacuum machines directly connected to the mold through pipes, and a filter cloth is installed inside the mold. The filter cloth is mostly made of glass fiber cloth or non-woven fabric, and the filter cloth can prevent sewage, sundries, cement thinner, etc. from entering The vacuum machine can effectively protect the vacuum machine, but some dirt will always enter the vacuum machine, causing damage to the vacuum machine and shortening the service life of the vacuum machine

Furthermore, since the filter cloth is relatively soft, the laying process of the filter cloth is cumbersome, and it is not easy to lay and fix, and the filter cloth is easy to stick to the cement slurry, and it has to be replaced after several uses, which greatly increases the production cost.

If the area of ​​the prefabricated part is too large, the vacuum machine will work all the time, and it is difficult to control the vacuum degree. If the vacuum degree is too small, the water cannot be sucked out. suction
